dart sport build

I just got a 1974 dodge dart sport with a 225 /6 for my first car and i want to know what i need to do to get more power and a better sound out of it. thanks.

I am currently on /6 Dart #3 !I violated my most simplest rule of all, and that is "KEEP IT SIMPLE STUPID" !! Shave the head .90,Offy 4bl Intake/390 carb, a small cam and a set of Hooker Headers and some Magna Flow mufflers and you should be happy for a while !! 'Till the bug hits you !!!
